Why are my analog sticks locked in place and torn up?

Dirt and Residue

Over time, dirt, dust, and other residual materials can get into the crevices between the joysticks. If you can identify the area that is dirty, and you have canned air, give the area a quick blast. This might disrupt the debris enough to knock it out of the controller. If this doesn't work you may need to clean the joysticks from the inside. To do this, follow the steps in the 'analog stick replacement repair guide.

Joystick Has Been Bent or Broken

If none of the above steps fix the problem, it is likely that your analog stick(s) is bent or broken. In this case, you’ll need to order a new analog stick from Sony or another distributor, then follow the analog stick replacement guide.
